Description
Technical Field
The utility model relates to an automatic control technical field especially relates to a novel resistance box automatic regulating apparatus.
Background
At present, the test process that the resistance box participated in all is the manual regulation resistance value, and the single can only be adjusted a frequency channel resistance value, and the manual participation can appear adjusting numerical value inaccurate situation moreover, and the reading is also not enough directly perceived, especially when appearing the error, is difficult to audio-visual discovery problem.
SUMMERY OF THE UTILITY MODEL
The utility model provides a novel resistance box automatically regulated equipment, resistance value that can automatically regulated resistance box to carry out visual display with the resistance value.
In order to realize the utility model discloses an aim, the technical scheme who adopts is: the utility model provides a novel resistance box automatic regulating apparatus, includes outer box, display screen, PLC and servo motor, and the front at outer box is installed to the display screen, and PLC and servo motor install in the inside of outer box, and PLC is connected with servo motor and display screen electricity respectively, and servo motor is used for adjusting the knob position of resistance box, and the resistance box is arranged in outer box.
As the optimization scheme of the utility model, servo motor is 6.
As the utility model discloses an optimization scheme, servo motor's motor shaft passes through the regulating spindle of shaft coupling and resistance box and links to each other.
As the utility model discloses an optimization scheme, novel resistance box automatic regulating apparatus still includes resistance converter, and resistance converter is used for converting the resistance value into the RS485 signal, and resistance converter's input links to each other with the output terminal of resistance box, and resistance converter's output links to each other with the display screen.
The utility model discloses has positive effect: 1) the utility model can be installed on the existing resistance box, can simultaneously adjust the resistance values of 6 frequency bands through the display screen, does not need manual adjustment, is rapid in adjustment, saves time and labor, and avoids deviation when manual adjustment is carried out;
2) the utility model discloses a resistance converter, display screen can show current each frequency channel resistance, can the discovery problem directly perceived when the regulation mistake appears, and the reading is direct-viewing.

Detailed Description
As shown in fig. 1-2, the utility model discloses a novel resistance box automatic regulating apparatus, including outer box 1, display screen 2, PLC and servo motor 4, display screen 2 installs in the front of outer box 1, and PLC and servo motor 4 install in the inside of outer box 1, and PLC is connected with servo motor 4 and 2 electricity of display screen electricity respectively, and servo motor 4 is used for adjusting the knob position of resistance box, and the resistance box is arranged in outer box 1. Wherein, outer box 1 still is provided with the terminal, and is corresponding with the terminal of resistance box, during the use, only needs to work a telephone switchboard on the terminal of outer box 1, need not to dismantle equipment, safe and reliable, the simple operation, but outer box 1 direct mount is convenient for integrate on current resistance box.
The number of the servo motors 4 is 6. The motor shaft of the servo motor 4 is connected with the adjusting shaft of the resistance box through a coupler 5. Through 6 servo motor 4 of PLC control, servo motor 4 can rotate the knob of resistance box, can adjust the resistance value of 6 frequency channels simultaneously, adjusts rapidly, labour saving and time saving. The servo motor 4 can be controlled by a PLC controller, the servo motor 4 can also be controlled by a corner setting unit and a corner switching unit together, the corner setting unit is used for receiving the resistance value set by the display screen 2, the corner switching unit is switched among a plurality of corner values according to the resistance value, and the corner setting unit and the corner switching unit can be realized by using a special integrated circuit or a programmable logic device.
As shown in fig. 3, the novel automatic adjusting device for the resistor box further comprises a resistor converter, the resistor converter is used for converting the resistance value into an RS485 signal, the input end of the resistor converter is connected with the output binding post of the resistor box, and the output end of the resistor converter is connected with the display screen 2. The resistance value of the resistance box output is input from VN 0.
When the device is used, a required resistance value is input from the display screen 2, the PLC controls the servo motor 4 to rotate by a corresponding angle according to the input resistance value, and then the resistance converter converts the resistance value into an RS485 signal and outputs the RS485 signal to the display screen 2.
The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
